tion 3 being inclined upward and to the left iroin the central rib and the strands in section 4 being inclined upward and to the righ-t. l 5 The cent-ral rib in the torni shown in Figs. l and lis slightly corrugated transversely so that the expanded section from beain to beam vis of substantially uniform thickness. ln the forni shown in Fig.. 5 the cental l0 rib is groored longitudinally so that the channel faces in the saine direction the channel 6 in the inain ribs or beams.

The strands it will noted stand in a lgcneral'edgewise direction relative to the plane of the fabric, the strands iii section 8 being tilted particularly at tlieir bonds or points ot' connection 14- and l5 upward toward the right as viewed in F 2 While the bonds in p section 3 are tilted upward toward the left. rl`his insures a better distr'bution of the cement, plaster or mortar. r lie small sized diamond inesliivorl; also tends to distribute Y ofinclination of the strands of each section corresponding to the direction of inclination of that edge of the adjacent bea'rn with which they are united. This structure has the strands bent directly from the lianged 40 edges without tivistingvand thus avoids strain in manufacture. lt also means that the niaxiinuin strength of the nietal `isavailable to resist strain when in use. lt will be obvious that the fabric inay be of any Width or length and have as inany beams and reticulated sections as desired.

lil hat I claim is As a new article of. manufacture, a `slitted and expanded sheet ymetal,structure,

cons ing of slitted and uiislitted portions, ,and loving relatively deep y,ribs consistingvr ot' beir". unslitt'cd portions oit the nietal, an

i unslitii'd strip intermediate ol the deep ribs, at least sonie of the deepliibs liavii'ig their edges'adjaccnt `to theslitted portions ieversely bent and facii'igf the opposite side of the structure from theA deep ribs tlicinselves and oppositely directed slats `connecting said strip and the edges of said deep 'ribs substantially as described. i

2. As a new article ofy manufacture, a slitted and expanded sheet metal structure, consisting of slitted and unslitted portions,

. an A. hai/ingr relatively deep spaced ribs consisting of bent unslitted portions of the inca-,fire

nietal, a central strip between cach pair oi' deep ribs the inner edges oit tbe deep ribs being reversely bent so to face in the opposite direction iroin the deep ribs theniselves and two series oi' slats ci'inncrtinp, said strip with the reversely bent edges ot said.

deep ribs, substantially as described.

3. As a new article of manufacture, a` slitted and expanded sheet inetal structi'fre consisting" oit slitted and unslittcd portions and haring deep ribs consisting` oi bent unslitted portions of the metal, said ribs liaving relatively narrow reversely bent lips at their edges, a cent 'al iinslitted strip and a series of oppositcly directed slats connecting said strip with said reveisely bent lips, the outer portions of the deep ribs having perforations therein substantially as described.

4f. An expanded metal fabric consisting` o?? longitudinally corrugated ribs having; ieversely bent edges forming channels facingj in opposite directions and an eni'ianded metal section connecting;v 'the reversely bent edges and consisting of' two parts united midway between the 'corrugated ribs, tbe strands of the tivo parts being inclined in opposite directions.

5. An ein'ianded inetal fabric consisting; of longitudinally corrugated ribs having re-l versely bent edges forming channels facing in opposite directions and an expanded metal section connecting the reversely bent edgesand consisting of tivo parts united midway between the corrugated ribs'7 the sides of the ribs having' openings so constructed so as to prevent the formation lines of cleavage.,

G. il. i'eticulated nietal fabric consisting el' longitudinallyl corrugated ribs having versely bent edges fori'nintnv channels facing in the opposite direction, tbe sides of the ribs being' perforated to 'permit cenicnt or plaster to be interlcclred through the same and a reticulated section connecting tbe reversely bent edges of the ribs and consisting of strands With relatively sinall openings therebetween. v

'Z'. An expanded inetal Jfabric consisting' of longitudinally corrugated ribs having' reversely bent edges forming channels 'far 'in opposite directions and an expanded metal section connecting: the revcrsely bent edges and .consisting of two parts united' niidway @tween the vcorrii..p,'ated ribs, said expanded metal section consistinpl of bent strands Ainclined edgewise to the general plane of the fabric and connected together to forni substantially diamond-shapcd niesli- Work, the strands of the said two parts of the section being' inoline'd in opposite directions.

S. vA reticulated metal fabric, comprising beam inenibers each having a relatively deep inain channel portion with rerersely bent
